IMPRVEMENT EN SEINNING MACHINE T0. WHOM IT MAY CONOERN':

Be it known that we, JOSEPH HAM', SARAH HART, and JOHN Rnnsamn, of -Farmington, in the county of p Van Buren, and State of Iowa, have invented a Domestic Wool-Spinner; and we do hereby declare the following Vto be a full, clear, and exact 'description thereof, reference being had tothe accompanying drawings,.making' part of this specification, in whichl Figure 1 is a plan view of the improved wool-spinner.

Figure 2 is an elevation of one side o f the'same.

Figure 3 is. a longitudinal section taken' through'thc upper portion of the spinner in thevertical plane indicated by red line'y y in fig. 1.

Figure 4 is a transverse section taken through the spinner in the vertical plane indicated by red line a: :t in iig. 1. I I Similar letters of reference indicate corresponding parts in the several'iigures.

'.This invention relates to 'certain novel improvements on domestic or hand-spinning machinery, `which are designed for simplifying `and rendering such machinery more eiiicient in its'operation. v

The nature of` our invention consists in a novel means for moving the carriage carrying theroping clamps during the operation of drawing and spinning, and `of automatically stopping the motion of said carriage at a proper time for ceasing the drawing operation, as will be hereinafter described. i i

The ,invention also consists in a clamp for holding the roping during the drawing and `spinning operations, which is so constructed that each roping is embraced between two semicircular jaws, and thus held iirmly,'so that none of the fibres are allowed to draw through, as will be hereinafter described.

It also consists in providing for unwinding the roping from its spool during a portion of the backward movement of the carriage, by means of sidebars which have anendwisc and vertical movementmand which are operated' by arms upon said carriage, as will be hereinafter described. i

To enable others skilled in the art to understand our invention, we will describe its construction and' operation.

In the accompanying drawings,'A represents the frame of the machine, which is adapted for containing and supporting the several parts employed in the operationl of clamping,-dra`wing, and spinning the raping. B

is a. driving-shaft, carrying a hand-crank, Bl, and n. belt-wheel, B2, over which latter the belt a passes and communicates motion to the pulley a and its horizontal transverse shaft b.

The shaft carries upon it a number-'of grooved pulleys ec c c', around which belts d d or cords pass that communicate motion to the several spindles e e. These spindles c e have their 4upper and lower bearings in a frame, C, which is pivoted at both ends between the uprights of the main frame, so as to oscillate about said .pivots as indicated in iig. 3, in which view the dotted lines indicatethefra'me-*C in an uprightposition for Ywinding the twisted yarn upon the spindles or spools placed thereon, and the full lines indicatethe frame in an inclined position for spinning and twisting the yarn. In order to allow the frameC to be moved in said positions without causing the bands d d to run off their pulleys' c e on spindles e e, or becoming loose thereon, 'we arrange the axis of motion of said frame in line withJthese pulleys, and vthus keep the driving-bands always under proper tension to rotate the spindles, whether the frame C be inclined or in an upright position. The spiudle-carrying frame C is inclined during the backward movement of the carriage, to which` the ropings are clamped, and during the drawing and spinning operation, and this frame is brought to an upright position for the purpose of allowing the spun yarn to he wound upon the spindles and the carriage to be moved forward by this winding-up operation. A handle or4 lever, C', upon one end of the spindle-frame `C, is used for adjusting' this frame, and suitable stops upon the frame determine its proper positions.`

Upon the rear uppermost rail of the frame A, and properly attached thereto, rests a horizontal. frame, l), the two parallel side rails of which constitute tracks and guides for the rollerf and wheelsf' of a. carriage, E, which travels backward and forward, toward and from thespindle-frame, during the operations of spinning, drawing, and winding. The outer end of the track-frame D may be supported upon the standard D' or in .any other suitable man-ner. 4 V

The carriage E is provided with a friction feed-roller, F, upon its rear'end, having its end bearings in standards F F upon the sides of said carriage, and this roller is arranged so that it will just clear the rail track.Y Above this roller and resting freely upon it is the spool G, carrying the ropings, the ends of which spool are guided in/slcts made inthe standards F', so that by means of two'cords, y g, vand a winding crank-rod, gl, the spool can be raised and removed from the machine when it is emptied of its ropinfgs.

Infront of the roping-spool is an endless apron, H, which passes around rollers, one of whichis provided with a handerank, g2, by which this apron'ca-n be turned and the roping moved from thc'spool up to a clamp, which is used for holding cach roping separately during the spinning and drawing operations, as will behereinafter described. i

Upon each side of the traclcframe D-wc apply a longitudinal bar, J, which is slotted, and fastened in place in the manner shown, or in anysuitablc manner which lwill allow this bar to be moved endwise and at the same time raised and lowered; Upon each one of these bars J, and applied at or near the extremities thereof, pins iz'project, which are acted upon by a curved arm, J', on each side of the carriage E. When the carriage is drawn forward and arrives near the end of its forward stroke, the arms J lstrike the pinsz" and move both bars J forward and upward, so that, when the carriage ismoved backward, the upper edges of these bars J will cause the-roller F to revolve, and thus unwind a certain quantity of roping from the spool G, which rests freely upon it, as above described. When suflicient roping has thus been unwound from spoolI G upon 'the apron H, the pins z' are so arranged that the arms J" strike them, and thus move the bars J J backward and downward out of the way, so that the carriage can proceed backward the required distance without further movement of roller F. Pin@ t'z" may-be made adjustable, so that the positions can be changed according as circumstances require.

The elamp'K, which confines the ropings during the drawing and spinning operations, consists of two parallel plates, Z Z, secured together so as to. leave a narrow space between them, in which is placed aslidingplate, fm, that is moved in a direction with its length by a shortvibrating arm, n., shown in the figs. 1, 3, and 4. The'upper edge of this clamp is notched, as shown at p p, the notches corresponding in number and distance apart'to the spindles c e, and these-several notches terminate in circular holes p', which are made through thc threeplates forming the clamp. When the intermediate notched and perforated plate m is adjusted so that its notches and holes arev in lines with those inthe plates Z Z, the ropings are drawn into saidl holes through the notches and confined at such points by moving the plate m. By thus confining each roping strand between circular clamps, all the fibres of each strand will be closely held, and all the strands will be uniformly clamped. Formovng the carriage backwardduring'the drawing and spinning operations, we employ an'automatic contrivance for stopping the movement of said carriage when it reaches a position far enough for the spindles.

Thisrcontrivancc islas follows: Upon the horizontal shaftl b, and between the two double pulleys'c c thereon, a loose drum, r, is placed, which has a number of holes made in one end for receiving studs that project from one end of one of the grooved pulleys c when said drum is moved up to this pulley. When' thus engaged with the pulley c', the drum r will turn with its shaft b.. Two forked armss s project down from a horizontal transverse rod, M, at both ends of SaidV drum r, as shownl in fig.y 4, so that, by giving this rod an endwise movement, the drum 1' will receive a. corresponding movement, whether at'rest or rotating,and thus the drum can be engaged or disengaged at pleasure. v I

The rod M has a lever, N, applied to it, .by means of which a person standing near the hand-crank B can move the rod forward, and thus bring the loose drum Tinto gear with its fast pulley c; at the lsame time the hooked pin t will drop down and hold the rod M and drum 1' in the adjusted position. j

Directly Aover the rod M is a lever, P, which is pivoted to the frame A, so as to vibrate freely.` One end of this lever l? is arranged beneaththe hooked end of pin t, a-nd the other end has a cord, w', fastened to it, which passes under the drum r and is carried' backward around a pulley, u, at the rear end of the track-frame D, and attached to the'lower end of tire-lever T, shown in tig..3, Ysheet 2. I One end of a cord, w, is attached to and wound around the drum r, and the other cnd'is passed under. and over the pulley u 4and attached to the bottom of the 'carriage-frame D, as shown in lig. 3, When'the drum 1', its rod M, latch-pin t, and lever P are in positions abovcdescribed, and shaft b is turned, the cord w will be wound upon drum r, and the carriage-E moved backward until it strikes the upper arm of lever T, when this lever, through its cord fw', will draw down the inner end of lever-P, andl thus raise the latch-pin t. When this pin t is raisedso as to release the rod M, a spring, t', shown infig. 4, will force this rod backward and release the drum r from its pulley c', so that the carriage E will stop. The carriage having been stopped, the spindleframe C is brought to an upright position, as indicated inv dotted lines, iig. 3, which will cause the spindles to Wind up the spun yarn, and thus movethe carriage back to a 'positionfor commencing the operation of drawing and spinning again. i

We are aware that it is not new to employ parallel bars as clamps for holding roping during the operation of drawing and spinning, and we do not claim such contrivances as our invention. The clamp which we have herein shown and described is s'o constructed that each roll is clanipcd'and heldA separately but uniformly, und is embraced by semicircular edges, so that allA the {ibreswill be held firmly, whereas with s traight-edged-clamps this is no t the case.

Having described our invention, what We claim as new, and desire to secure by LettersfPatent, is p '1. The arrangement of the combined clutch and dr'um 1, for controlling the motion of the carriage, with the spindle-driving shaftand its pillleys, substantially as described, I

2. The tripping-lever T, cord w', lever P, latch-pin ,'and spring-rbd M, carrying arms 8 s, in combination with a drum, r, whichis provided witha clutching d evice,'all being arranged and constructed in such manner that when the carriage presses against the lever T, the drum r will be made loose upon its shaft, and this carriage caused to stop further backward movement. v

` 3. The ropiug clamp K, constructed lof' plates Z l and an intermediate slidingplate m, notched and perforated, substantially as described. y

4. Providing for unwinding the roping from its sp'ool G, during a portion of the backward movement of A the carriage E, by means of a. friction-roller, F, and vertically and endwise movablc bars J J, which latter are l actuated by` thc arms J on` the carriage, substantially as described. Y
